It feels strange rating a book so highly when I can honestly say I spent half the time wondering what the hell was going on. Everyone's name ended in a vowel, everyone was getting killed on every other page, everyone had a given name as well as a nickname, and on and on it went.
Hey, so this is a book about a made man, Gregory Scarpa, Sr., who is turned by the FBI, and his handler is a dude named Lin DeVecchio. Needless to say, from the title of the book, neither of the two are on the up and up. Scarpa doesn't tell the entire truth to the FBI and *gasp* makes sure what he does tell the FBI suits his situation. DeVeccihio uses his in with the mob to, well, get in with the mob, you'll see.
Another thing about Scarpa is that he has full-blown AIDS through-out much of his life due to a transfusion, so that adds a little twist.
Then, to make things even MORE confusing, the author, Peter Lance, he of the fully-researched book (no kidding, wow, holy cow), shows at the end how if the FBI would just stop investigating the dying mafia already, they totally could have prevented 9/11. Look, it's hard to explain in a book review because I'm not very good at book reviews, but Peter Lance does a great job of it because he is very good at writing well-researched books. I'm going to read all of his books now. Heck, I even read his footnotes at the end, and I never do that, because who the heck cares about footnotes.
